While children scream with delight at the many waterparks in Wisconsin Dells, you can soak up the quiet serenity of this eco-friendly resort tucked away in a 26-acre pine forest that caters only to adults.

The Sundara features electronics-free common areas, 26 spa-inspired suites with king featherbeds, villas deep in the woods, an adjoining 18-hole golf course and chef-prepared meals using farm-fresh ingredients. Activities to help you recharge include swimming, hiking, kayaking, biking and yoga.

No children. No smoking. No telephones. No Internet. Nothing but plenty of peace and quiet at the Midwest’s only "Relais & Chateaux" (translation: luxury!) property, situated on 280 acres of beautiful woodland.

A free continental breakfast is delivered to your door in the morning. And meals in the glass-enclosed dining room overlooking the lake are prepared with fresh produce from the resort’s very own garden and orchards.

You definitely won’t find children at this entertainment venue, where you have to be old enough to vote to get in. The Skyline Comedy Club attracts some of the top comedians in the business, so laughing out loud is pretty much guaranteed.

Tickets must be purchased in advance on their website. And there is a two-beverage minimum per person, per show.

Legally, children aren’t allowed in casinos, so going gaming is a sure bet for an adults-only night out on the town. In Green Bay, try your luck at the Oneida Casino, owned by the Oneida Tribe of Indians of Wisconsin.

Take in free live music and choose from eight dining and drinking venues. The casino is located inside the Radisson Hotel, so if you’re having too much fun, you can always stay the night.

Find beer, cheese, sausage—and did we mention beer?—at this popular Milwaukee brewery. Learn how their legendary drafts are made during a 45-minute tour. Lakefront Brewery is famous for pumpkin beer, and it was the first U.S. brewery to bottle a fruit beer after Prohibition.

While you may see a kid or two, they must be accompanied by an adult at all times.

Plan a memorable night out at this popular wine bar in Waukesha. Crush offers a large selection of wine, including some you’ll be hard-pressed to find in other shops. Pair your favorite vintage with cheese and chocolate for a truly decadent evening.

Classes, private tastings and local entertainment are served up, too. Consider becoming a club member and you’ll receive discounts on select bottles and club events.
